The Iceland Greenhouse Restaurant is positioned in a landscape influenced by sandy ground movement and varied terrain. The design uses a modular approach that incorporates a series of connected buildings, allowing for flexibility in development. This layout encourages visitors to explore the site, creating interaction between the surrounding environment and the various spaces within. The restaurant serves multiple purposes, including dining, kitchen operations, and greenhouse facilities, all arranged to offer a cohesive experience.

Design Concept and Layout

The layout introduces a pathway that directs visitors across different levels of the terrain, highlighting the natural topography. Each building is carefully oriented to align with the landforms, fostering a sense of harmony with the external landscape. This arrangement not only promotes exploration but also encourages patrons to engage fully with the setting while enjoying the restaurant’s offerings.

Architectural Composition

The structure consists of various functional areas, featuring an entrance hall, dining room, bar, open kitchen, greenhouse, and storage spaces. Additional elements, such as staff rooms and terraces, enhance operational efficiency while creating a welcoming environment. The design prioritizes user experience, making it easy for guests to navigate between spaces, ultimately promoting both social interaction and individual comfort.

Sustainability and Construction Approach

The project emphasizes sustainability, a focus that is apparent in the construction methods. The greenhouses are built using a modular system of recycled steel frames, showcasing an efficient and environmentally friendly approach. Three-column cross-sections act as structural hangers for vegetable growth, directly linking agricultural elements to the overall design. This strategy strengthens the relationship between the building and its use, encouraging an active engagement with food production.

Development Phases

A phased development plan outlines future growth, starting with the main restaurant and two greenhouse units. Subsequent phases include a multipurpose hall and further facility expansions. This structured plan ensures that the design can adapt over time, meeting the evolving needs of its users while responding to the specific characteristics of the site.

As visitors approach the restaurant, they can observe the vertical divisions on the façades, which create a dynamic interplay of light and shadow. This visual detail enhances the building's character while establishing a connection to the thriving environments found within the greenhouses.

Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
